Specification of Letters Patent.

Patented Feb. 16, 1909.

Application filed June 11, 1908. Serial No. 437,978.

To all whom it may concern:

Be it known that I, GEORGE W. MAYBERRY, a citizen of the United States,residing at Philadelphia, State of Pennsylvania, have invented certainnew and useful Improvements in Devices for Releasing Horses and Cattlein Case of Fire; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being bad to the accompanying drawings, and to theletters of reference 'marl ied thereon, which form a partof thisspecification.

This invention relates to new and useful improvements in apparatus forreleasing stock from stalls in case of emergency, such as fire, etc.,and comprises means whereby one or more animals may be automaticallyreleased by suitable lever-actuated mechanism, comprising variousdetails of construction, combinations and arrangements of parts whichwill be hereinafter fully described and then specifically defined in theappended claims.

1 illustrate my invention in the accompanying drawings in which Figure 1is a side elevation of my improved apparatus showing the retainingdevices in locked ositions and in dotted lines in released positions,and Fig. 2 is an enlarged perspective view showing the means for hol ingthe apparatus in a set position.

Reference now being had to the details of the drawings by letter, Adesignates a wall and B artitions between which are stalls, and Cesignates a shaft which has a longitudinal movement through apertures insaid partitions. Fastened to said wall be tween each pair of partitionsis a plate D having integral lugs D projecting therefrom which areapertured and mounted upon said shaft are the collars E, each of whichis provided with a set screw E whereby the collar may be held in a fixedposition upon the shaft. A ri ht angled rod F is fixed to each of saidcofl ars and has a horizontally disposed portion, said horizontallydisposed portions of the rods being in alinement with each other andadapted, as the shaft carrying the same moves longitudinally in onedirection, to engage the apertures in the lugs 1) upon the plates D andform pivotal means upon which the ring carrying members H are mountedand to the rings upon which members the animal is designed to befastened in any suitable manner. Mounted upon said shaft C is a coiledspring K, one end of which is fastened to a bracket N upon said wall andthe other end secured to a pin 0 passing through an aperture in the rod.A lever J is pivotally mounted upon a pin J carried by the plate L, and

Q designates a collar which is mounted upon 2 the shaft G and held in anadjusted position thereon by means of the set screw Q. A lug R projectsfrom said collar Q and has its upper edge tapering.

A spring .8 is fastened at one end to one of the partitions dividing theapparatus into stalls and has a lug S upon its under face which isadapted, as the shaft is moved longitudinally in one direction, tocontact with the inclined surface of the lug or projection Q, upon thecollar Q, causing the spring S to yield until the lug projecting fromthe latter passes the outer end of the'lug Q, after which the springwill return to its normal position with the lug S in engagement with theouter end of the lug Q, thus holding the shaft at its farthest throw tothe left. A. wire T is fastened to one end of the spring S and its otherend secured to an angled lever T pivotally mounted upon the pin T uponsaid wall, and T designates a second angle lever pivotally mounted uponthe wall and connected to the angle lever T by means of a wire T. A rodor wire T is connected to the angle lever T and a handle '1 secured tothe wire T 5 affording means whereby, as an operator pulls down uponsaid rod T the spring S may be released from the lug R and allow thespring K to return the shaft C to its farthest limit to the right, inwhich position the angled rods engaging the ring holding members willbewithdrawn from the ring holding members and the animals therebyreleased. Projecting from the collar Q is an eye Q through which saidlever passes and in which the lever works in resetting the shaft ormoving the same in its farthest direction to the left. A pin Q projectsfrom the lever against which the eye is adapted to contact after theshaft is returned by the coiled spring to the right. Said eye (Q, comingin contact with the pin Q will limit the movement of the collar Q, inone direction.

The operation of my invention will be readily understood and is asfollows :The various ring holding members being interposed between thelugs D with the apertures in registration, tudinal movement to the leftby sw ngnig the lever to an upright position. This movepass by the lug Safter which the resiliency of the spring S will cause the lugs S toserve as a stop to hold the shaft C in a set- .position or in itsfarthest position to the left. 'When the shaft is in a set position, the

' spring K will be under tension, the same being a coiled spring and,when it is desired to release the ring carrying members to which theanimal is adapted to be fastened, the operator by pulling upon thehandle T may cause the spring S to release the shaft and allow the sameto move to the right which movement will allow the angle rods to movefrom the ring carrying members as will be readily understood.

While I have shown the two angle levers and connections with thereleasing spring, it will be understood that the connections with saidreleasing spring may extend to any suitable location whereby theapparatus may be released near by or a distance from the location wherethe animals are confined.

What I claim to be new is 1. A device for releasing stock from stallscomprising, in combination with a wall, plates secured thereto andprovided with apertured projections, a horizontally and longitudinallymovable shaft, rods projecting therefrom and having portions which arein alinement with the apertures in said projections of the plates, aspring fastened to said shaft and adapted to normally hold the same sothat the rods thereon will be out of engagement with said aperturedprojecthe shaft 6 is given a long'itimes 'of the plates, a pivotallever, an eye projecting from the shaft through which said lever passes,a pin upon said lever, adapted to engage said eye upon the shaft a lugupon said shaft, a resilient catch having a lug adapted to engage thelug upon said shaft, and means for releasing the catch to allow thespring to actuate the shaft and cause the angled rods thereon towithdraw from the apertured projections of said plates, as set forth. 7a

2. A stock releasing apparatus comprising a wall, plates fastenedthereto and each having alined apertured projections, a horizontallymounted longitudinally movable shaft, collars upon the latter, setscrews carried by said collars and designed to engage said shaft, anangled rod projecting from each collar and each having a portion inalinement with each other and adapted 'to register with the apertures insaid projections, apertured ring carrying members, each adapted to bepositioned between said fprojections with the aperture therein inregistration with the apertures in the latter'for the reception of oneof said angled rods, a coiled spring secured to said shaft which issli'dably mounted upon said wall, an eye carrying collar'upon the shaft,a pivotal lever passing through said eye, a .pin projecting from thelever to engage the eye in one position of the lever, a lug upon saideye carrying collar, and a resilient catch having a lug designed toengage the lug upon said collar, and means for releasing said catch, asset forth.

In testimony whereof I hereunto afliX my signature in the presenceof'two witnesses.

GEORGE W. MAYBERRY.
